Hello fellow communitie users, I would like to create a Revit Family on every point of a block (selected) form a linked DWG. I have seen two topics like it but i don’t know how to implement it. From: @Azubike_Ononye > [@CAD Block Insertion Point to Family location](https://forum.dynamobim.com/t/cad-block-insertion-point-to-family-location/13478): > > Hey guys - I am looking to retrieve the insertion point of a block in an active AutoCAD file and use that to locate revit families. These are nodes from the LinkDWG package. As seen from the image below, the node within the green box works perfectly showing the layers and the layer colors. However, for some reason the node within the blue box isn’t reading CAD file. I have also attached the python file driving the ActiveX.GetCOMObjects node.

Right now, I’m using an Excel file got from AutoCad and then I use dynamo to insert a family instance by point. I would like sth without using Excel, because those Cad blocks have geometry parameters with the location, so if I could read them, it’s gonna be faster than create an Excel file and… I’ve tried with ActiveX package ans DynamoCad package, but nothing works.

Hi you just need to import your CAD and explode it partially, use @john_pierson’s code to get Points. ---

If you explode it will give a lot off pollution and slow down the moddel but thanks a lot for the tip 😄 ---

A custom node is now available: “CAD Block”. It is now easier to batch place familyInstances at each block insertion point from a linked DWG. (without exploding the DWG or \_DATAEXTRACTION from Autocad or reading AutoCAD file with ActiveX) ![FamilyInstances from CAD Link](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/6/669bcbf21c9818d30edc518c83e4e68c933f79c1.gif) ![FamilyInstances from CAD Link2](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/a/fa654964560fe4465b32fdb3b4bc0d255950d584.png) ---

Hi @Alban_de_Chasteigner it’s powerful, thank you very much for you python node. Do you have any node to get also the dynamo geometry? Cheers ---

Hi Stefano, This is possible to get the geometry. There is already the _CAD.CurvesFromCADLayers_ node of BimorphNodes package. ![CAD to curves](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/d/cd480f5212f3415ea65ee82cbbb819ee2be9e065.png) What kind of geometry do you need ? ---

Hi @Alban_de_Chasteigner ,thanks for your answer, I would like to get the Geometry from the link or imported DWG (into project or family environment) like the output of “Element.Geometry”, “Element.Solids” or “ImportGeometriesByCOM” (“Mesh” for example) Cheers ---

Hi @Alban_de_Chasteigner , thanks for your answer, yes of course but for more complex geometry (3D DWG exported from others mechanicals programs like SolidWorks, Solid Edge, Catia, Inventor) it fails or dynamo crash, for this I’m looking for another method to get the external geometry surface into RFA or RVT (python or maybe with Grasshopper for Revit) and work in background, there are some workaround and plug-ins (for example the method “shrinkwrap”) but it’s more time consuming for thousant families. Thanks for your efforts Cheers ---

Hi @Alban_de_Chasteigner - The Origin Point output of your CAD Block node is not reading the block insertion point in my case, but instead is reading an origin point in the CAD file that is the same for each block instance. So, if I were to run the script to place family instances for each block, then they would layer multiple instances onto the same origin. I have tried using the LinkDWG2 nodes for BlockProperty to acquire the insertion point, but cannot seem to figure out why I am getting “null” values for these nodes. Any advice or help that you can share would be greatly appreciated. Thanks, Ryan ![Forum help_CAD Block to Family Instance](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/9/09358564cfddb8388ac4abd365a47af9f19982a3.jpeg) ---

Hi @yaella, Welcome to the Dynamo forum. It is not possible to help you without viewing the warning messages and previews under the nodes. Apparently, your families are not named exactly like Autocad blocks since they are not found by the _Family.ByName_ node. ---

Hi @rgoold18_SSA, Welcome to the Dynamo forum. It’s interesting. You would have to share your DWG file (possible by private message) so that I understand its structure and the problem. ---

You can export those type of files as SAT files, which are made of solids and or surfaces that can be read by basic nodes of Dynamo. I did in some occasions with STL, OBJ file format, like a mesh file to open in Dynamo. [Next page](https://forum.dynamobim.com/t/autocad-block-to-revit-familie/23100.md?page=2)
